If you have never been to the University of British Columbia Museum of Anthropology in Vancouver, BC, Canada, you should save some money and go. Their ceramics collection is vast and wonderful. I spent over five hours there looking at it all. If you cannot go, you are in luck because they have an online collection (although, it is much more amazing in person).
The empty bowls project is a charity made possible by artists and non-artists. Check out the details and get INVOLVED!
